<u>Answer:</u>
Events A and B are not independent because P(A|B) ≠ P(A).
<u>Step-by-step explanation:</u>
We are given that the probability of a student scoring 75% in class work is 0.64, and the probability of a student scoring 85% is 0.45.
Given that a student scores 85%, it means he must have scored 75% too.
It means that event B is dependent on event A.
Therefore, events A and B are not independent because P(A|B) ≠ P(A).
Answer:
80mph
Step-by-step explanation:
200 divided by 2 1/2 is 80.
So for 12.5 meters...the little guy walks 5 meters per minute....
<span><span><span>12.5meters</span><span>5<span><span>meters</span><span>minute</span></span></span></span>=2.5minutes</span>
we can check it by saying...okay...if his speed was 5 meters per minute....and he walked for 2.5 minutes...does he walk 12.5 meters?
<span>5×2.5=12.5</span><span>
so yes it checks out :)</span>
